Cladding metal

Claim 1

A METHOD OF CLADDING METAL ARTICLES WITH A METAL SELECTED FROM THE GROUP CONSISTING OF TIN, LEAD, CADMIUM, ZINC, ALUMINUM, MAGNESIUM, COPPER, SILVER, GOLD AND ALLOYS THEREOF, WHICH METHOD COMPRISES MIXING SAID ARTICLES WITH PIECES OF IMPACTING MATERIAL IN A LIQUID CARRIER CONTAINING PARTICLES OF SAID SELECTED METAL IN AMOUNT SUFFICIENT TO PROVIDE A DESIRED THICKNESS OF CLADDING METAL ON SAID ARTICLES AND IN PROPORTION RANGING FROM 1/480 TO 4/3 OF THE COMBINED WEIGHT OF SAID ARTICLES AND IMPACTING MATERIAL, SAID CARRIER LIQUID BEING IN AMOUNT BETWEEN .143 AND 100 OF THE WEIGHT OF THE METAL DUST PARTICLES AND INCLUDING DISPERSED THEREIN AN ORGANIC SURFACE-ACTIVE, FILM-FORMING COMPOUND UNREACTIVE WITH SAID CARRIER LIQUID AND SELECTED FROM THE GROUP CONSISTING OF THE FATTY ACIDS OF 6 TO 22 CARBON ATOMS AND THE AMINES AND AMIDES OF SAID ACIDS, SAID COMPOUNDS BEING PRESENT IN AMOUNT IN THE RANGE OF THE ORDER OF .7 TO .001 OF THE CARRIER LIQUID BY WEIGHT AND AT LEAST SUFFICIENT TO SUBSTANTIALLY COVER SAID ARTICLES AND TO ENCLOSE AND PROTECT THE POWDER PARTICLE SURFACES WITH MOLECULARLY THIN FILMS, FORCIBLY IMPACTING AND RUBBING SAID FILMCOATED DUST PARTICLES IN ADMIXTURE IN SAID CARRIER LIQUID ONTO THE SURFACES OF SAID ARTICLES TO FLATTEN SAID PARTICLES AND RUPTURE SAID FILMS AND BRING THE PARTICLES IN METAL TO METAL CONTACT WITH THE SAID SURFACES AND WITH EACH OTHER, THE TEMPERATURE OF THE TREATING CARRIER LIQUID BEING AT LEAST EQUAL TO THE MINIMUM TEMPERATURE OF RECRYSTALLIZATION OF THE SAID METAL PARTICLES TO CLAD SAID SURFACES WITH ADHERENT SURFACE LAYERS OF SAID FLATTENED PARTICLES WITH ENTRAPMENT OF RESIDUAL INCLUSIONS OF SAID FILM-FORMING COMPOUND RETAINED IN RANDOM DISTRIBUTION AMONG SAID FLATTENED PARTICLES OF SAID CLADDING LAYER, AND CONTINUING SAID IMPACTING AND RUBBING OF SAID FILMCOATED PARTICLES ONTO SAID ADHERENT SURFACE LAYERS TO BUILD UP SAID SURFACE LAYERS TO DESIRED THICKNESS ON SAID ARTICLES.
